The Schedule referred to in these Letters Patent and making par of the same- To all whom it may concern:

Be it knowntbat 1, O. KAIBEL, of Sacramento City, in the county of Sacramento, and State of California, have invented a new and improved Apparatus for Drying Malt, 850.; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification, in which drawing. I

Figure 1 represents a longitudinal vertical section of this invention.

Figure 2 is a transverse section thereof, taken in the plane indicated by the line as x, fig. 1.

Similar letters indicate corresponding parts.

This invention relates to an apparatus for drying malt, and other materials of a similar nature, which is composed of one or more drums, that are made of perforated sh eet-metal, and provided with an internal spiral flange, and a perforated tubular shaft, and the ends of which are fitted into stationary caps in such a mannerth'at said drum or drums can be revolved in their bearings, and that malt, grain, or other materials of a similar nature, fed into the drum'at one end, will be carried through to the opposite end.

With the perforated tubular shaft connects a suction-blower, for the purpose of exhaustingthe moisture; and the feed of the malt, or other material, to the revolving drum or drums is rendered automatic by cams projecting from the drum, and acting, through suitable levers, on a gate in the feed-channel.

The drum or drums are enclosed in a furnace; and,

when two or more drums are used, they are placed one above the other; and they communicate with each other by means of tubes extending from the cap of one drum to that of the other.

The dust which disengages from the malt or other material during the process of drying, collects in an inclined trough at the bottom of the furnace, whence it can be readily removed;

A represents a furnace, which is built up of brick, or any other suitable material;

IGn theinterior of this furnace are secured the caps O 0' 0' form the bearings for the drums B B.

These drums are providedwith internal spiral flanges, l) D, which are firmly attached to the inner surfaces of the drums, and to the outer surfaces of the perforated tubular shafts E E..

One end of the shaft E is open, and extends, through its cap 0, into a pipe, F,which connects with the fanblower G; and the other end of said shaft is closed by a plug, H, which extends through the end of the furnace, and on which is mounted a'gear-wheel, a.

On the circumference of the drum B, near one of its ends, is a series of cams, I), (see fig. 2;)-and, as the drum revolves, these cams actuate a system of levers, 0, whereby the gate (1 is opened at regular intervals.

After the levers c are released from the action of the cams, they close the gate by their inherent gravity.

Said gate passes transversely through the feed-tube e, through which the material to be dried is fed to one of the caps O, and, .by the cams b and levers c, a uniform feed is obtained, which requires no attention.

As the drum B revolves, the material to-be dried is carried. through it by the action of the spiral flange D, and it discharges through a trunk, 1, leading from the cap 0* to the cap 0 of the drum B.

The open end of the tubular shaft E extends through the end of the furnace, and on it is mounted a gearwheel, a, which meshes into the gear-wheel a on the shaft E, (see fig. 1,) so that the two drums revolve in opposite directions.

The opposite end of the shaft E is closed by a plug, H, which extends through the cap 0*, and through the end of the furnace, and turns in a suitable bearing.

From the cap 0* extends the discharge-tube J, out through the side of the .furnace.

When the fan-blower G is set in motion, a current of air is produced, which passes in through the open end of the shaft E, and yout through the spout of the blower-case, and, by these means, all the moisture risingfromwthematerialkm be driedisranidlyexpelled, and the drying-operation is materially facilitated.

The furnace Ais provided with a fire-place, K, which communicates, through'lateral tubes f, (see fig. 2,) with the interior of the furnace, and the heat, rising from the fire, is prevented from rising straight up by the diaphragms g h, so that the same is compelled to spread uniformly throughout the entire furnace.

end of the furnace.

In this trough collect the dust and impurities, which the material to be dried, and, by opening said door,'the impurities can be readily removed.'

By this apparatus, the operation of drying malt, grain, or other materials of a similar nature, can be effected with little trouble, and a uniform product is obtained.

I do not claim as my invention the arrangement of a such having been known heretofore; but, having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The stationary caps G 0* and perforated hollow shaft E, in combination with the perforated drum B and fan-blower Gr, substantially as and for the purpose described.

2. The arrangement and combination of the furnace. A, blower G, caps G 0* 0' O drums B B, perforated hollow shaft E E, trunk I, and discharge-tube J, all substantially as and for the purpose set forth.

3. The inclined trough L', in the lower part of the furnace A, .in combination with the perforated drums B B, substantiallyas and for the purpose set forth.-
